What I can help with

Explore the service areas.

Independent consultancy
01

Wireless & switching

Business Wi-Fi and UniFi Network

Plan, deploy and improve wired and wireless networks, from gateway and PoE-switch selection to access-point placement, coverage and guest isolation.

  • UniFi gateways, switches and access points
  • Wi-Fi coverage, RF tuning and roaming
  • VLANs, guest networks and segmentation
  • Multi-site device adoption and troubleshooting
02

Management & reliability

Self-hosted UniFi controllers

Operate and maintain a customer-owned or independently hosted UniFi Network control plane, with attention to secure access, backups and device continuity.

  • UniFi Network / supported UniFi OS Server
  • Controller migrations and restore planning
  • Remote administration and multi-site visibility
  • Updates, monitoring and backup verification
03

Guest access

Hotspot and captive-portal systems

Create guest Wi-Fi experiences with clear access policies, captive portals and the right authentication or voucher model for the venue.

  • Branded portals and hotspot onboarding
  • Voucher-based and time-limited access
  • External portal and RADIUS integrations
  • Guest isolation, usage policies and reporting
04

Physical security

UniFi Protect and Access

Explore and plan camera, recording, door-entry and access-control deployments using compatible UniFi hosts, hardware and site infrastructure.

  • IP camera coverage and PoE planning
  • UniFi Protect cameras, NVR and recording design
  • UniFi Access door readers and entry workflows
  • Permissions, connectivity and maintenance planning
05

Voice & communications

PBX and business telephony

Help design and configure IP telephony solutions, including UniFi Talk, 3CX and Grandstream equipment and PBX systems, based on site requirements.

  • 3CX and Grandstream PBX/VoIP systems
  • UniFi Talk and compatible handsets
  • SIP trunks, extensions, IVR and call routing
  • Provisioning, network QoS and troubleshooting
06

Wider infrastructure

Networks, hosting and operations

Connect communications equipment to the infrastructure that keeps it dependable, including routing, structured networks, monitoring and recovery.

  • MikroTik, UniFi/UISP and multi-vendor networks
  • VPNs, gateways, VLANs and firewall planning
  • Linux, Docker and service hosting
  • Backups, monitoring and operational documentation

A practical approach

From first assessment to handover.

Projects vary, but the goal stays the same: understand the environment, agree on the scope and leave behind something maintainable.

  1. 01 / 04

    Discover

    Understand the site, users, coverage, connectivity and constraints before recommending equipment.

  2. 02 / 04

    Design

    Map the network, equipment, guest policies, voice and security needs into a reviewable plan.

  3. 03 / 04

    Deploy

    Configure, adopt and test the approved scope, including connectivity and access controls.

  4. 04 / 04

    Support

    Document the setup and discuss practical monitoring, backups, updates and future growth.

Getting the architecture right

One ecosystem. Different hosting needs.

A self-hosted UniFi Network controller is not the same thing as hosting every UniFi application on a general-purpose server. Cameras, access control and telephony may require their own compatible UniFi hosts and hardware.

UniFi Network / UniFi OS Server

An independently managed network control plane can help with device adoption, configuration, backup and multi-site administration.

UniFi Protect, Access and Talk

Camera recording, doors and communications are planned around compatible hardware, supported hosts and each product line’s requirements.

3CX and Grandstream

Independent PBX options are evaluated separately from UniFi Talk, with carrier compatibility, SIP setup and operational needs checked before deployment.

03Planned

Better Wi-Fi without simply adding more access points

Coverage, RF interference, channels and roaming.

04Planned

Have a site or system in mind?

Start with what needs to work better.

Whether it's an office Wi-Fi rollout, a hosted UniFi Network controller, guest hotspot, cameras, doors or business phones, share the context and we can discuss the right scope.

Independent services. Brand names are used to describe compatible product families; no official manufacturer partnership or certification is implied. This is not a contact channel for my employer.
